Wrong charge for data and over R20 for an email?

I just got off the phone after a VERY long argument with Raymond Mojapelo - I have asked to speak to his manager however he chose to not put me through to him...I got charged R220.07 for data that I didn't use. I switch off my phone's data and connect to wifi at work and home...I check my balances on almost a daily basis and now somehow on one day I get charged R220.07 and no further explanation can be given to me - please deduct this amount from my bill. Raymond then sent me an email and has subsequently failed to mention that he will charge me over R20 to send this mail to me - so now my bill for this month is higher again
